A man was arrested on Friday after accusations that he made threatening phone calls to Democratic officials.

John Kless, 49, of the Fort Lauderdale, Florida, area, reportedly left vulgar messages rife with racist and anti-Islamic rhetoric on Tuesday. Kless ranted about gun rights, 9/11, and illegal immigrants, per The Washington Post. He also threatened the lawmakers with violence.

Among the recipients of the threats were Reps. Rashida Tlaib (D-Mich.), Eric Swalwell (D-Calif.), and Sen. Cory Booker (D-N.J.). In all three messages, Kless mentioned "hatred" for Rep. Ilhan Omar (D-Minn.), though he reportedly did not call the congresswoman herself. Kless' threats were made following several other alleged death threats specifically targeting Omar. She said they have increased ever since President Trump posted a video consisting of graphic footage of 9/11 edited together with clips of Omar making comments for which she has been criticized for downplaying the tragedy of the attacks.

Kless appeared in court on Friday and was released. Arraignment is set for May 3 in Fort Lauderdale. Tim O'Donnell
